Now I have run the C benchmark and Ed's. My results are:
| Program | # iterations | time (s) | speed (K/s) | factor |
|--------------+--------------+----------+-------------+--------|
| ansi c | 150e6 | 133 | 1127.8195 | 1. |
| perl | 1.5e6 | 56 | 26.785714 | 42.1 |
| my pdl | 15e6 | 67 | 223.88060 | 5.0 |
| Ed's pdl | 15e6 | 16 | 937.5 | 1.2 |
| Ed's 4 cores | 15e6 | 11 | 1363.6364 | 0.8 |
So, as Ed wrote, just by stting and environment variable,
perl+pdl+pp_def can be made faster than c.
